Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.

To produce this patch I did all of the following:

1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.

2. Run ./mach lint --linter black --fix

3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.

4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.

5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

Bug 1633712 - [devtools] Add test cases to browser_target_list_tab_workers and remove the fission fail-if. r=jdescottes.

Check that when removing iframes, we're notified about the worker unregistration,
and check that the target list works as expected when we have multiple iframes
on same origin (both remote and same-origin as main document).

The test documents are modified so we can avoid spawning shared and/or service
workers (in the case of this test, this seems to prevent some memory leaks/crashes).

Bug 1633712 - [devtools] Create WorkerTargets as soon as possible. r=ochameau,devtools-backward-compat-reviewers.

This patch adds support for dedicated worker targets in the Watcher actor.
Shared and Service workers are not handled yet.

In a similar manner to what we already have for frame targets, we add a worker-helper
file that will communicate with a JsWindowActor pair spawned on each document,
that will  manage workers (DevToolsWorkerParent/DevToolsWorkerChild).

For a given document, the DevToolsWorkerChild will enumerate the existing workers
related to it, as well as add an event listener to be notified when workers are
being registered and unregistered, and communicate that back to the DevToolsWorkerParent
on the main thread, so worker targets creation and destruction are notified by
the Watcher actor (via target-available-form and target-destroyed-form events).

When a worker is created, the DevToolsWorkerChild for the document the worker
was spawned from will create a WorkerTargetActor, that will live in the worker
thread (using worker-connector.js), passing it resources the Watcher is currently
listening for. It will also handle communication between the main thread and the
worker thread, when the watcher listen to new resources (or stop watching resources).

A WorkerTargetFront is created so the client can be notified about available
resources (via the resource-available-form event, emitted from the worker target).

Tests are added in the next patches of this queue.

Bug 16706178 - Part 2: Make the CORS preflight cache partitioned by the originAttributes. r=ckerschb,necko-reviewers

We want to partition the CORS preflight cache by the network state
partitioning. So, we have done two things in the patch. First, we make
the CORS preflight cache to be aware of the OriginAttributes. Second, we
use the originAttributes of the network state partitioning in the CORS
preflight cache. As the result, the CORS preflight cache will be
partitioned by the originAttributes.partitionKey as well as other
originAttributes fields if present.
